乳腺癌中Survivin和Ki-67的表达及其临床意义

目的 检测Survivin和Ki-67在乳腺癌中的表达,探讨两者的相关性及临床意义.方法 应用免疫组织化学法检测49例乳腺癌组织和12例正常乳腺组织中Survivin和Ki-67的表达.结果 Survivin和Ki-67在乳腺癌组织中的表达阳性率明显高于正常乳腺组织中的表达(P<0.05);Survivin的表达与患者的临床分期、淋巴结转移有关(P<0.05),而与其他临床病理特征无关;Ki-67的表达与患者的临床分期、淋巴结转移和病理学分级有关(P<0.05),而与其他临床病理特征无关;Survivin和Ki-67在乳腺癌组织中的表达呈明显相关性(r=0.734,P<0.05).结论 Survivin与Ki-67可能通过相互协同作用参与乳腺癌的发生、发展过程,可作为评价乳腺癌生物学行为的重要依据.

The expression and clinical significance of Survivin and Ki-67 in breast carcinoma

Objective To investigate the expression and clinical significance of Survivin and Ki-67 in breast carcinoma,and explore their correlation.Method The expression of Survivin and Ki-67 in breast carcinoma(49 cases)and normal breast tissues(12 cases)were examined by immunohistochemical method.Results The positive expression rates of Survivin and Ki-67 in breast carcinoma were significantly higher than those in normal breast tissues(P<0.05).The expression of Survivin was significantly related to clinical stage and lymph node metastasis(P<0.05).The expression of Ki-67 Was significantly related to clinical stage,lymph node metastasis,and pathological grade(P<0.05).The expression of Survivin was obviously related with Ki-67 in breast carcinoma(r=0.734,P<0.05).Conclusions The overexpression of Survivin and Ki-67 may play a cooperative role in the occurrence and development of breast carcinoma.They may serve as useful markers for assessment of biological behavior of breast carcinoma.
